When the supply voltage is switched on, the PNOZmulti safety system copies the configur­
ation from the chip card.
The LEDs "POWER","DIAG", "FAULT", "IFAULT" and "OFAULT" light up on the base unit.
The expansion module PNOZ m ES Profibus is configured and started automatically. The
"ONLINE" and "OFFLINE" LEDs indicate the status of the PNOZ m ES Profibus on
PROFIBUS­DP.
If the expansion module PNOZ m ES Profibus does not receive a configuration from the
base unit for a period of 30 s, the expansion module PNOZ m ES Profibus connects to
PROFIBUS­DP and "ONLINE" status is displayed on PROFIBUS­DP. The error message
"No Connection with Base Module" is sent to the Master.
